Rename binary: shellfu-doc to sfdoc

'sfdoc' is easier to type and resembles 'pydoc' and 'perldoc' so it's
even easier to remember.

 And that's also *all* this command does.
 
 Next, if you have also installed some modules, you can look around
-using `shellfu-doc`:
+using `sfdoc`:
 
-    shellfu-doc --lsmods
-    shellfu-doc inigrep
+    sfdoc --lsmods
+    sfdoc inigrep
 
 This is how you access documentation of modules available on the system.
 You can also access documentation of a modules directly by specifying
 path to the file (the path must contain slash):
 
-    shellfu-doc path/to/my/module.sh
+    sfdoc path/to/my/module.sh

 Guide, in particular the Docstrings section.
 
 Next, you can create your first Shellfu-Bash script:

     shellfu will figure out where exactly it is.

     `warn` and `die`.

 To get the basic stuff, nothing more is really needed.  If you want, however,
-your module be explorable by `shellfu-doc`, you need to follow Shellfu Style
